I had AWFUL luck with my Ranger. Transmission internal bearings went out (even after religious fluid changes) rearend had all sorts of issues, body parts fell off, spring perches rusted off, lots of electrical misfits..Blew a headgasket and ate batteries right after the warranty like clockwork. rear brakes had to be replaced every two years... That was a 1998 2wd 2.5 5speed. Never could do better than 23mpg. SUCH a SIMPLE truck! And SO much went wrong it was sickening! The sad part is, I took care of it so well and it didn't return the favor.
The newer 2.3 Duratec trucks are much better engine wise I heard can pull close to 30. I am not sure I will ever own another Ranger again after that beating though. WTF.
However, I've have terrible luck with every car I've had except the Jeep.
Look at it this way... having a second car costs a ton of money. In order for having the second car to pay off fuel wise, you should throw a calculation at it.... You will go back out to sea and that car will sit there, racking up insurance and car payments etc...
For instance, I bought a subaru station wagon to replace driving my jeep. I have spent $3500 for the parts I had to get on the car so far, and it has a really bad rod knock now so I need a $1000 motor. So instead of spending $4500 on gas this year with the jeep, I've wasted about $7300 CASH on gas and trying to save gas.
You are probably richer than me and have better luck though.
